• Contribute to improving our front‑end developer experience, including building tools, testing practices, and performance optimisations
• Ensure technical decisions support our goals of quality, performance, reliability, and security
• Work with and contribute to open source codebases, including evaluating, extending, and maintaining shared libraries and tools where appropriate

• You enjoy mentoring and supporting others, and you contribute positively to the team’s culture and technical growth
• You stay up to date with modern tools and approaches without being dogmatic. Your goal is to find the right solution, not the trendiest one
